When you observe ST elevation in multiple contiguous leads but the patient has no symptoms, which step is appropriate?

• A. Verify tracing accuracy and repeat ECG.
• B. Administer thrombolytics immediately.
• C. Assess for artifact and escalate if STEMI is confirmed.
• D. Ignore the tracing if asymptomatic.

Answer: (C)

ST elevation seen across several contiguous leads requires confirming that the tracing is accurate before deciding on treatment. In an asymptomatic patient, you don’t assume STEMI—you first check for artifact or lead problems (loose or misplaced leads, poor skin contact, baseline wander) and repeat the ECG if needed to determine whether the elevations are real. If, after this, the ST elevations are confirmed as genuine and fit a STEMI pattern on serial ECGs and clinical context, you escalate to STEMI protocol promptly. Giving thrombolytics or other invasive therapy without confirmed STEMI can cause harm, while ignoring the tracing would miss a potential serious event.
